This may sound like a stupid question. And I'm pretty sure I already know the answer (at least somewhat). Right now, the soundcard that I am using (Tascam US-428) only has 2 outputs(a Left and a Right). I'm really considering upgrading to a Delta 1010 and I'm wondering what the use of so many outputs is. Can someone please explain these to me? Thanks in advance for your help. This forum is great.
